Title: Junction field effect transistor and fabrication thereof
Inventor: YANASE SABUROU
IPC: H01L29/808
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To accurately control the characteristics, e.g. saturation drain current and pinch-off voltage by forming an embedded layer, such that it is located on the interface of a semiconductor substrate and an epitaxial layer through high energy ion implantation, thereby determining the channel thickness uniquely. SOLUTION: An N-type epitaxial layer 2 is formed on a P-type semiconductor substrate 1 and a P-type insulating diffused layer 3 is made through the N-type epitaxial layer 2. Boron ions are then implanted at high energy over the entire surface of a wafer. A boron ion implanted layer, i.e., an embedded boron layer 8, serving as a back gate is formed across the interface of the P-type semiconductor substrate 1 and the N-type epitaxial layer 2. Subsequently, boron ions are implanted selectively from the surface of the N-type epitaxial layer 2 to form a P-type top gate diffused layer 4. Finally, an N+-type source diffused layer 6 and an N+-type drain diffused layer 7 are formed to complete an N- channel JFET. According to the structure, saturation drain current IDSS and pinch-off voltage VP of the JFET can be controlled easily.

Title: Method and system for spread spectrum communication of spread code automatic recognition type
Inventor: IIMORI RYUICHI
IPC: H04B1/7073
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To conduct spread spectrum communication, without setting a specific regulation relating to a spread code between a transmitter and a receiver. SOLUTION: A spread spectrum transmitter 1 transmits a signal spread by a prescribed spread code. A transmission reception section 2 converts a received signal into a signal which is a base-band signal and provides an output of it to a spread code detection section 3. The spread code detection section 3 controls a spread code generating section 4 to sequentially output a plurality of codes to establish correlation with the received signal. The correlation is executed until a correlation value, that is outputted when the spread code is coincident, is detected.  When a code used by the transmitter side is detected by the retrieval of the spread code, an initial synchronization discrimination section 5 establishes synchronization with the received signal, by using the code and a carrier recovery section 6 recovers the carrier of the received data and provides an output of the demodulated data.

Abstract: PROBLEM TO BE SOLVED: To provide the demodulator hardly causing inter-symbol interference in the case of receiving a plurality of radio waves by one antenna under a single frequency network(SFN) environment or receiving the radio waves under a multi-path environment. SOLUTION: In the demodulator of a receiver that receives an orthogonal frequency division multiplex modulation signal, a PRS symbol is extracted from an output of an FFT circuit 3, resulting from Fourier transformation to a reception signal. A cross power computing element 7 is used to obtain a transfer function of a transmission line at a frequency point, where a carrier exists, the obtained transfer function is given to an IFFT circuit 8, where inverse Fourier transformation is conducted to obtain an impulse response signal. An adder 12 is used to obtain the sum of impulse response signal levels in a window for a period with a time period nearly equal to a guard interval period length, deviated sequentially in effect, and a peak position detector 13 detects a peak position at which a peak is generated from an output of the adder 12.  A phase of a sampling pulse signal of an A/D converter 1 is shifted, based on the peak position so as to be converged into an objective position for controlling the reception timing.
